The researchers, who repeated the experiment many times, also showed that the new, bioengineered teeth were fully-functional.
Dr Kazuhisa Nakao said: 'Every bio- engineered tooth erupted through the gum and had every tooth component such as dentine, enamel, pulp, blood vessels, nerve fibres, crown and root.'
Importantly, the rodent recipients had no trouble eating.
If the technique can be used in humans, dentures may eventually be obsolete. The tooth shown in the picture also had a green fluorescent gene so it could be seen easily. Link -via Digg
